Abstract (en)

In a coating evaluation device and a coating evaluation method, a coating surface is irradiated with incident light having a first intensity distribution, and a second intensity distribution of light reflected from the coating surface is acquired. Additionally, a third intensity distribution associated with the second intensity distribution is calculated on the basis of a curved shape of the coating surface, and an evaluation value that corresponds to the third intensity distribution is estimated by using an evaluation model that outputs a brilliance evaluation value pertaining to the coating surface in response to an input including the third intensity distribution.
